/**
 * E2E: live "Multibyte only" toggle.
 *   1. Toggle exists in live controls and defaults OFF.
 *   2. With it ON, a single-byte synthetic packet does NOT create a feed item,
 *      while a multibyte one does.
 *   3. Turning it OFF and rebuilding shows the previously-hidden single-byte pkt.
 *   4. The setting persists across a reload (localStorage round-trip).
 *
 * Usage: BASE_URL=http://localhost:13581 node test-live-multibyte-only-e2e.js
